Abstract
The invention relates to a system for treating blood, which includes a single cassette capable of carrying out the various CRRT treatments.
Claims16
A medical pump system comprising:
- a disposable cassette having a pump;
- and
- a reusable apparatus having a drive device configured to cooperate with the pump of the disposable cassette,
- wherein the drive device includes a floating shaft having a rotational axis rotatably driven by a drive means, the drive means configured to be coupled to a motor rotor having a motor axis of the reusable apparatus,
- wherein the floating shaft includes a cavity inside which the drive means is at least partially circumscribed,
- wherein the drive means includes a body configured to cooperate with internal walls of the cavity to limit an orientational freedom of the rotational axis of the floating shaft relative to the motor axis to compensate for tolerance errors of the pump, and
- wherein the cavity includes a cooperation element allowing the drive means to apply a rotation movement to the floating shaft.
